Recently there have been impressive experimental demonstrations of
individual conductive molecular wires and molecular electrical switches.
The next logical step toward the development of an electronic computer
integrated on the molecular scale is to incorporate several such molecular
wires and several such molecular switches into a single molecular circuit
structure designed to perform a simple digital computation, such as
addition [1,2]. The speaker will describe the results from quantitative
analyses of designs for such conductive monomolecular circuit structures.
For example, this molecular circuit analysis reveals that molecular
electronic circuits are likely to switch and to compute better than
analogous micron-scale, solid-state circuits. The speaker also will
discuss research which has resulted in the development of a prototype
software tool for performing these molecular circuit analyses. The tool
provides a graphical interface in which one can assemble a model of a
molecular circuit structure, for which it analyzes the electrical
performance. This tool has been tentatively named "MolSPICE", since it
performs analyses for molecular circuits that are similar to those
performed by the well-known and widely available SPICE tool that is used in
the analysis of microelectronic circuits.
